On 09/09/2000, I wrote this text for a discussion group among veterinarians. What would we say about this subject today?
Of something around 1500 infectious diseases cataloged by the World Health Organization, 200 are Zoonoses (diseases communicable from animals to humans).
The epizootiological and epidemiological behavior of certain newly emerging diseases, such as those caused by the Ebola virus, the Australian equine Morbillivirus, the Hantaviruses and the “Prions”, has generated some alarm in World Public Health.
However, the inconstant level of seriousness of action of the Health Surveillance, in the different levels of contingency, national, state and municipal, is what generates the determining factor of the appearance of epidemics or epizootics.
In a world scenario where globalization of activities merely focused on the commercial aspects of a devouring and elitist capitalism is discussed, it is up to us to scrutinize the stertorous yearnings of a sick and anemic Public Health in the Third World.
National health and agricultural defense policies, luxurious and extravagant in essence, created in a laboratory, disconnected from basic structuring actions aimed at collective health, are nothing more than technocratic premises and philosophical guidelines, totally divergent from the real peripheral contexts of “Africa”, “India” and “Brazil” with its droughts and mangroves, postcards of world misery.
Partnerships are created (G-7, “Merco of this, Merco of that”) with surrealist objectives, with the sole beneficiaries of powerful merchants, holders of maximized structures in “Markets” of capitalist life.
In this enigmatic context, Health (animal health and human health) is lacking and Zoonosis (anthropozoonosis and zooanthroponosis) begins to exceed.
And where are the health professionals who promised to always obey, in the exercise of their noble profession, the postulates of science, honor and charity?
Certainly, lost in dreams and ideals of mercantile practices, devoid of the basic principle of love for others, which should be embedded in their professional duties.
Many within the area of ​​Public Health, create slogans and raise theoretical socialist flags. Being a Socialist is not preaching Marxism, communism and other “ideological aphorisms”, but following the simplicity of what is written in the biblical reference of John 13.34-35.
We need to pay more attention to World Public Health and to study and evaluate daily the progress of these Zoonoses, which seem to threaten the evolution of medical science human resources with greater speed and better strategy.
My question is:
In your opinion, why are zoonoses gaining greater repercussion in current public health? Has medical science awakened to the real problem? Was it driven by conflicts of interest? Or did it just reduce some bias in your and hypotheses?
Relevant answer
Answer
Zoonoses are a growing concern due to a number of variables, including their frequently unique and unpredictable nature, their capacity to appear anywhere and spread quickly throughout the world, and their significant financial impact on a variety of dissimilar industries, as well as economic losses due to medical care and absence from work due to illness.

Relevant answer
Answer
You know Chilgoza pine is one of those species that grows in harsh environmental conditions and it produces a deep root system that is why it evolved in harsh conditions. Producing a deep root system is one of the strategies to grow in harsh environmental and edaphic conditions. I think the low survival rate in artificial regeneration is damaging of the root system and unfortunately, we don't care much about the root system. In the nurseries, we can improve shoot growth maybe with fertilizers application and other provisional practices.

Question

I am making use of a multiphase mixed-methods study to develop, implement and evaluate an injury surveillance system.
In the first study, I am making use of an exploratory sequential design, where the participant's perceptions (qualitative approach) will be used to build a context-sensitive framework, through which quantitative data (weekly survey) about injury rates can be captured (second study). Since the quantitative part is a longitudinal study, collecting data from the same population, I am also analysing the end-users engagement with the system, based on the weekly response rate.
At the end of this, I will be evaluating the surveillance system as a practical tool for end-users through qualitative data (third study). This will be done by analyzing response rates from the prior quantitative study and identifying a purposeful sample of participants based on their response rates and their engagement with the system.
Now, the question is, should I call this design a sequential explanatory one? I am confused as I am only using one outcome (weekly engagement) from the second study and trying to explain it through qualitative means.
Relevant answer
Answer
It sounds you basically have a three-step design: qual --> QUAN --> qual. Such designs are quite reasonable but relatively rare. Hence, it does not have a standard name, but you might all it "an intervention study that includes both exploratory and explanatory components within a mixed methods framework."
My book on "Integrating Qualitative and Quantitative Methods" includes a chapter on three-step designs.

Question

With the daily updates on COVID-19 cases and deaths, I am trying to understand the algorithm behind the assignment of the cause of death.
I was wondering how doctors evaluate and assign the cause of death?
E.g. if someone has a heart attack, following COVID-19 infection (while they are infected - not post recovery) and this person had metabolic syndrome (let's say all dyslipidemia, hypertension and hyperglycaemia) how to we make a decision if the cause death is COVID-19 or diabetes or cardiovascular disease?
To me the guideline given for the assignment of COVID-19 death in Australia seems to have an inherent bias towards COVID-19:
"As per the COVID-19 national guidelines, a COVID-19 death is defined for surveillance purposes as a death in a probable or confirmed COVID-19 case, unless there is a clear alternative cause of death that cannot be related to COVID19 (e.g. trauma)."
But I actually do not wish to restrict my question to COVID-19. Instead, I am trying to understand in general how we calculate mortality rates for different diseases, as these numbers inform policy and how funds are allocated.
Especially for complex metabolic conditions, like cardiometabolic ones, how do we decide if someone with type 2 diabetes, and vascular damage potentially due to hyperglycaemia, that had a stroke, will be assigned to the diabetes deaths toll or to the cardiovascular deaths toll?
How does e.g. WHO come up with:
9.5 million deaths from heart attack per annum
6 million deaths from stroke per annum
2 million deaths from diabetes per annum
Is there a guideline given to doctors regarding a decision-roadmap to assign the cause of death?
Relevant answer
Answer
How to assign cause of death during the COVID-19 pandemic era?
Because of early over-reporting and under-reporting of deaths assigned to COVID-19 early during the era of this pandemic, now there has been guidelines that may help. However, to assign as particular event as a cause of death due to COVID-19, autopsy is the best method, a practice more recommended than actually done. The challenges in doing post-mortem studies during the COVID-19 stem from problems with logistics, availability of experts, and fear of transmission of SARS-CoV-2 due to issues supplies of the required PPE around the world.

-Rapid risk assessment: Pediatric inflammatory multisystem syndrome and SARS -CoV-2 infection in children
-The ECDC has published a Rapid Risk Assessment on pediatric inflammatory multisystem syndrome and SARS -CoV-2 infection in children.
-According to ECDC, several countries affected by the COVID-19 pandemic recently reported cases of children that were hospitalized in intensive care due to a rare pediatric inflammatory multisystem syndrome (PIMS). The presenting signs and symptoms are a mix of the ones for Kawasaki disease (KD) and toxic shock syndrome (TSS) and are characterized, among others, by fever, abdominal pain and cardiac involvement. A possible temporal association with SARS-COV-2 infection has been hypothesized because some of the children that were tested for SARS-CoV-2 infection were either positive by polymerase chain reaction (PCR) or serology.
-The ECDC noted that about 230 suspected cases of this new pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 infection (PIMS-TS) have been reported in EU/EEA countries and the UK in 2020, including two fatalities- one in the UK and one in France. These cases are being further investigated.
-"So far, epidemiological studies have shown that children appear to be less affected by COVID-19. Only 2.1% of all laboratory-confirmed COVID-19 cases reported to The European Surveillance System (TESSy) were in the age group between 0 and 14 years of age", the agency stated.
-The ECDC also added that an association between SARS-CoV-2 infection and this new clinical entity of multisystem inflammation has not yet been established to date, although an association appears plausible. The ECDC assessed the risks as follows:
-The overall risk of COVID-19 in children in the EU/EEA and UK is currently considered low, based on a low probability of COVID-19 in children and a moderate impact of such disease.
-The overall risk of PIMS-TS in children in the EU/EEA and the UK – is considered low, based on a very low probability of PIMS-TS in children and a high impact of such disease.
-"While the clinical management of these children has absolute priority, data collection from EU/EEA Member States and the UK would strengthen the body of knowledge for this rare condition and allow for a better analysis of these cases. An analysis of surveillance data could clarify the incidence of KD/PIMS and identify the most affected age groups and risk factors for both conditions", the ECDC noted.
-ECDC has agreed with the EU/EAA Member States and the UK to include PIMS as a possible complication to be reported for EU-level COVID-19 surveillance. According to the agency, research efforts should aim at determining the role of SARS-CoV-2 in the pathogenesis of PIMS-TS and answering other significant remaining questions.

Immune mechanisms play an integral role in tumor growth establishment and metastases. Immunoediting is a dynamic process which contributes to immuno surveillance to keep under control It is made up of three phases: 1) elimination, 2) equilibrium, and 3) escape.
1. Elimination: Most immunologically vulnerable tumour antigens may eliminate by elimination phase immune editing as host’s immune system is capable of recognizing these cells
2. Equilibrium: However, constant division can generate tumour cells with reduced immunogenicity that can evade the immune elimination because of the genetic instability. This state of production of new tumor cell variants balanced by the distraction has been dubbed “equilibrium”, during which the cancer cells continue to divide, accumulating mutational changes by chance or in response to immune-induced inflammation.
3. Escape: These processes gradually come to a situation where tumours are capable of reducing the capacity of the immune system, to eradicate them by achieving immune suppressive effects or by loss of target antigen expression. Consequently tumour escapes from immuno surveillance and progression of carcinogenesis will occur. Nonetheless, there may be conditions under which tumor cells are truly dormant, for example by induction of “senescence”. In this case, they would be likely to remain dormant permanently, as replicative senescence is generally believed to be irreversible.
Microbiome studies based on ‘omic’ technologies have provided the laboratory evidence on disease associated in metabolic diseases and cancer (non infectious origin). These microbes especially bacteria are the most metabolically versatile organisms in the world, which can adopt to any environment, even changing their genetic potential, using mechanisms such as horizontal gene transfer. Thus cancer associated microbiome dominated by inflammaphilic periodontopathogens can be found in OSCC tumour micro environment.Furthermore, in-vitro experiments have provided substantial information on carcinogenicity of P. gingivalis and F. nucleatum.
I would like to start a meaningful discussion on immune responses of the host to 'cancerbiome induced inflammation' which can retard the 'immuno surveillance ' in oral carcinogenesis. For an example , retardation of 1st and 2 nd steps in immuno editing, which may cause immuno suppression, where tumour could escape from immuno surveillance. For an example well known periodonto pathogens such as P. gingivalis or F. nucleatum., how they can contribute to immuno suppression of the host which may lead tumour cells to escape from immuno surveillance ?

I'm currently employing a sequential mixed-methods approach, including an initial exploratory phase and a final explanatory phase. The initial phase is a qual -> QUANT, with the primary aim to understand the context of the stakeholders so as to design a context-specific surveillance system. The second phase is the collection of data through quantitative means and explaining it through the qualitative findings from the initial part, in other words integrating qualitative and quantitative findings. The third phase, i.e. the evaluation phase is a quant-> QUAL.
the question is: should I make use of a dialectic perspective, i.e. constructivism and post-positivism under the heading of pragmatism or should I explain this primarily from a pragmatism point of view, without considering the multiple paradigms?
Relevant answer
Answer
Creswell is not an expert on paradigms, and his advice is likely to cause you trouble if someone wants to know how you used constructivism as a basis for posts-positivism and vice versa. In any event, this statement does not say anything about a "dialectical perspective."
If you want to stay out of trouble in addressing this topic, pragmatism is the safer choice.

I am currently designing an intervention (injury surveillance system) to be implemented within an organization. This research (following a pragmatic paradigm) will follow a multiphase mixed methods research consisting of QUAL -> QUANT -> QUAL.
The initial qualitative part will be conducted through interviews with the stakeholders of the organization in order to understand their perspectives with regards to the intervention; to identify barriers and facilitators to implementing the intervention and to design the intervention that best fits with the organizational needs.
My question is this: I am not sure which qualitative approach do I have to consider in this first part of the study. I am approaching this study from a pragmatic world view and hence I do not know whether this part requires a specific qualitative approach.
Relevant answer
Answer
I agree with David L Morgan and Dean Whitehead that the most important thing to define is why you choose Pragmatism as the paradigm for your research. For example, I also conducted a multiphase mixed methods design for my doctoral research, which included an intervention. But while Pragmatism was the umbrella paradigm for the overall design of my research (w/ 4 research phases in total), the different phases of my project adopted different paradigms. For instance, whereas the phases with a QUAL priority adopted a constructivist stance, the ones with a QUAN had pragmatic stance.
The reason why I adopted pragmatism as the Overarching umbrella was precisely because one of its fundamental principles was paradigm integration, i.e. the synthesis of quantitative and qualitative standpoints. In short, the eclectic of pragmatism partners well with the multidimensionality of mixed methods multiphase designs, by allowing us the allocation of different paradigms along the different research phases of multiphase designs.

Data and accessibility services for persons with disabilities
Many people have privacy concerns particular data as more personal and sensitive than others, I think people's privacy concerns differ according to the purpose for which data is collected, with the contrast between service and surveillance purposes most paramount.
People must know for which purpose data is used and weigh the benefits that providing their data may offer them. When these benefits are of immediate personal relevance e.g. accessibility, medical, access services, I think most people are willing to share their data.
Relevant answer
Answer
"How important is the sharing of personal data for persons with disabilities?" is a complex question.
Data, I believe can be categorized into three classes.
1 - Personal (The stuff I don't want others to see),
2 - Private (The stuff that's okay to share with some others - Groups),
3 - Public (The stuff anyone can view).
Having a disability can make this modern age more difficult to navigate.
Many disabled people(s), Myself being one of them, have a handicap (for lack of better words) that restricts them from living average digital life. Whether having a physical or mental disability governs how easily it is for them to pickup new technology, understand it, and/or drive it to the next level, and is greatly influenced by current technologies, finance, and their abilities to assimilate technology. Not without saying, this is in vast contrast to the non-disabled that take these issues for granted.
It is very important to me (Being a physically disabled middle aged man), for me to be able to access and share my ideas and knowledge, as well as be able to access knowledge of new or old Technology, that makes our lives more complex every day as technology grows. However, this forces us into an everlasting upward slope to take in these technologies. Not just to understand how to use them (Which makes our lives easier and harder at the same time), but to also understand how to fix them. It is hard enough for the older generation that have no understanding of new technologies (Which they would rather it stay that way, and is a disability in it's own right), but to have other disabilities makes it more necessary for disabled individuals to share and access data across a wide variety of mediums, than not.
Further, disabled people often have their disability get in the way of doing average every day things, let alone having to understand new technologies that can be challenging without a disability being involved, in it's own right.
So, I believe the question should be:
How important is the protection of and security from, and for them to be, in relation to them; sharing of personal data for persons with disabilities, and the aging?
After all, senior citizens are constantly being phished, smished, and duped into giving out their credit cards and social security numbers among other sensitive details that are needed to access financials. And the aging do not understand that simply telling someone your dog's name, to a hacker can be very dangerous if your password is your dog's name.
This age of technology gets more complicated each and every day. We struggle just to have a comprehensive working knowledge to be able to work with it. Disabilities get in the way of carrying groceries to my car, let alone trying to access E-mail when my sciatic nerve is acting up. We either adapt and overcome, or we are left by the way side of this amazing modern lifestyle intertwined with technology, even when we do not see it.

Wireless sensor network (WSN) refers to a group of spatially dispersed and dedicated sensors for monitoring and recording the physical conditions of the environment and organizing the collected data at a central location. WSNs measure environmental conditions like temperature, sound, pollution levels, humidity, wind, and so on.
These are similar to wireless ad hoc networks in the sense that they rely on wireless connectivity and spontaneous formation of networks so that sensor data can be transported wirelessly. WSNs are spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. and to cooperatively pass their data through the network to a main location.

Basically you can use whatever you like (cameras, PIR sensors, ...). It's more or less a question of your surveillance objectives.
So, if using a Kinect is advantageous, why not. (Although, IIRC, the useable area of depth measurement is quite limited.)

In spite of several campaigns and infinite awareness activities, water wastage is still an avid problem. In countries like India especially in its rural areas, this problem imposes a great threat.
Is it possible to retrieve information relevant to this from the satellite image data and use it to build a systematic surveillance system for this?
Relevant answer
Answer
If you are willing to pay the costs for high resolution imagery like Worldview or Ikonos repeatedly, it certainly is possible at an excruciating amount. With opensource image its really difficult because of the coarse resolution. You can try using Sentinel-2 which is 10m to may be monitor the drainage systems. But the problem is in the rural areas these are very narrow and would not even comprise a single pixel on certain occasions. The best would be to use UAVs for monitoring, it wouldn't require a very sophisticated sensor so you could manage your budget also.

Hi everyone! My lab is in the process of establishing a new project involving the use of field-caught mosquitoes. Does anyone have any highly-recommended traps for catching mosquitoes in the field?
Our lab is located in a relatively swampy and humid area in South Carolina, so we have a large variety of mosquito species available.
Since we mainly use molecular techniques, we really need both the DNA and RNA of the captured mosquito specimens to remain intact.
Thus far, the most promising traps appear to be either the EVS 2801A CO2 trap (BioQuip Products Inc.) or a simple 2L cylindrical, insulated container with a CO2-baited miniature light, as was used by Paul DR Johnson et al. (2007).
Any information or recommendations would be immensely appreciated.
Thanks in advance!

Hi Lisa,
In Yucatan, Mexico (humid and warm state) we have used BG-Sentinel traps with octenol plus CO2 as attractants with very well results, collecting Culex spp., Ae. aegypti, Ae. taeniorhynchus and others in urban and sub urbans areas. Beside we used BG’s and CDC traps in different vegetation types in NPAs of Yucatan collecting 8 genera and 24 species of mosquitoes during 3 months sampling.
Regarding to DNA and RNA preservation you can use RNAlater™ just after you finish your sampling, add about 1 mL of RNAlater in an 1.5 mL Eppendorf tube along with the mosquito and storage it at -20 C or -80 C. Using this way the DNA and RNA of the mosquitoes could be stable for several months.

There are two approaches for molecular antimicrobial resistance (AMR) surveillance: 1.Typing-based, in which resistance is predicted by association with genotype, and 2. The direct detection of genetic markers of AMR.
If the prevalence of Neisseria gonorrhoeae is low in a city(for example 25-30 isolates during 6 month sampling), which approach is suitable for molecular AMR surveillance?
Relevant answer
Answer
Detecting and sequencing of AMR genes, is also an option, however that mean your selection of genes to be detected or sequenced will be based phenotypic characteristics of the isolates at MIC level. Some researcher also select the genes to be sequence based on previous history of existing resistance gene circulating within a geographical area. take for example blaCMY2 id very prevalent in North america while blaCTXM is more prevalent in Europe or bla metallo genes in Asia or India. So prior knowledge matters alot as well as phenotypic characteristics of the isolates derived from MIC reading.
If the resistance genes detected are associated with/specific to phenotypic characterictics of the isolates, and based on available information e.g. questionnaire survey or nationally collected data from routine surveillance, its possible to say frequent/continuous prescription maybe relating resistance.

how useful would you say genomic approaches is in this field in comparison to traditional methods used previously to identify pathogens?
Is it better for patient treatment for us to use genomic sequencing methods such as WGS/NGS? 
Does it help public health investigate outbreaks and make international surveillance easier?
Relevant answer
Answer
Dear Dr Ahmed
The short answer is yes. 
Genomics can be of use to identify an unknown pathogen. They can be used to trace the origin of an outbreak. They can with some difficulty be used to estimate the reproductive number. 
They can also be used to confirm/refute theories about the origins of an outbreak. C difficle is a problem in many hospitals. Although ribotyping suggested a common epidemic strain, further sequencing has shown that there are multiple strains circulating. Another example is MRSA. Although these strains have similar phage profiles, biotypes and resistance patterns there are multiple strains in circulation rather than one or two epidemic types. Finally a paper recently reported the results of an investigation into an extended beta lactam resistant Klebsiella pneumonia that has persisted for a several years. On analysis it was found that the strain had originated several years before it was detected in the hospital. 
All this having been said isolating the genome of an unknown pathogen can be difficult. This is at the moment not really sensible. Most labs are not set up to do this in real time so for the moment it seems we are stuck with the usual methods. There has been movement in this area for TB but the jury is still out on these for the moment. Inhibitors of PCR that are not allowed for in testing systems may produce false negatives or even worse false positives. All of that having been said it seems likely that these methods will become mainstream in the not too distant future. 
If urgent action is indicated the usual methods are probably the most reliable at the moment. When possible sequencing of the pathogens responsible should be done as this provides information that may be useful or even critical and cannot be obtained in any other way. For example say there is an outbreak of Salmonella at a party. Most food associated Salmonella have the same serology and phage type. While the usual methods of identification may suggest uncooked eggs (the usual suspect) legally this may be problematic given the similarities between Salmonella and the problems with growing them from the eggs days after the party. Genomic typing may even rule the eggs out as a source.

Relevant answer
Answer
 I wondered if anyone has tried a laser communication through water.
If it is for getting data from a camera I expect this will be a point to point link (and receiver and transmitter are stationary)?
The fundamental problem as explained above is that water acts like a conductor which  in general can be modelled as a plasma. Hence it should follow the Drude model for a plasma. The advantage however is that it is a relatively poor conductor so the plasma frequency should not be as high as that of metals. The link below suggests the plasma frequency of seawater is around 300GHz.
At frequencies above this the water should behave as a dielectric and the absorption is due to other mechanisms (e.g. free carriers) which is less that that predicted by the plasma drude model. However in practice since water is the great solvent that it is contains many impurities and the absorption curve needs to be measured. 
Doing a quick search on the internet suggests there is a huge null in absorption around 500nm (greenish blue light). 
A quick test might be to just get a green/blue laser around 500nm and measure the absorption of a water sample using an optical power meter. If you can get this to work all you need is a light modulator and you will have more bandwidth than you need.
If you know the actual plasma frequency for the type of water you have (and if it stays constant) there are lots of other interesting things you can do to overcome the classic skin depth problem. However plasma frequency is difficult to measure and you may need equipment around the 300GHz range of frequencies.
Good luck with your experiment.

The task you described in the last post actually consists of two parts: first, you need to detect if there are any new object in your frame, second you need to classify your object to understand whether this is human, vehicle or something else. For the first part alone any decent background subtraction method would fit, yoг can try something from here: https://github.com/andrewssobral/bgslibrary
The object recognition part is much more sophisticated, there is no universal recipe. Anyway, you will need some example data, extract features from detected objects and classify them using machine learning techniques. For standard tasks, like human body detection, you may try Haar Cascade based detector http://docs.opencv.org/modules/objdetect/doc/cascade_classification.html
You may find pre-trained cascades in OpenCV distribution, also some are available on the Internet, like here http://alereimondo.no-ip.org/OpenCV/34
